When Christopher Columbus discovered Haiti in 1492 he described a different Haiti, an island that has suffered centuries of exploitation and people who now live in the misery of over-population.

The Cousteau team discover in the waters around Cuba a richness that divers have not seen in any other part of the Caribbean Sea for at least twenty years. The team film the strange vertical position of the shark whale whilst feeding. Captain Cousteau also discovers in President Fidel Castro a common love of the sea.

Alcyone's debut and its first major test as a research and diving platform sharing duties with the Calypso. Alcyone and her team challenge the seas of Cape Horn, widely thought to be the most dangerous ocean passage in the world. The team film huge glactiers, giant crabs, huge albatrosses and tiny penguins. Alcyone herself nearly joins the victims of The Horn when she strikes a hidden rock.

Captain Cousteau and the crew of the Alcyone head northward from Cape Horn to investigate Mexico's fabled Sea of Cortez. The youngest and deepest of all the world's ocean gulfs; the seas is risch with marine creatures - birds and sea lions, fish and mammals. The Cousteau team compile the first complete record of the feeding behaviour of the elusive finback whale, the mating of the mama rays and spawning rites of the grunion.

The Cousteau team on board the Calyspo set sail for the South Pasific and the Marquseas Islands. Once hearty and independent, the people suffered death and destruction under the Spaniards and the Missionaries. Today, these fiercely proud people remain linked to the ancient rituals and customs of the past. The Cousteau cameras capture the beauty of the Marquesas from the highest waterfall in the Southern Hemisphere to mountain streams teeming with blue tropical fish.
